A STUDY ON CLINICAL PROFILE OF RIGHT VENTRICULAR MYOCARDIAL INFARCTION
Dr. S. Rajagopal and Dr. V. Rajesh Babu*
ABSTRACT
Coronary artery disease usually involves the left ventricle and acute myocardial infarction is almost always
associated with hemodynamic evidence of predominant left ventricular dysfunction although the right ventricle
may be involved in a reasonable proportion of patients dying with myocardial infarction. The lesion is usually
accompanied by left ventricular infarction. Involvement of the right ventricle is a common sequel of acute inferior
myocardial infarction, especially after proximal right coronary artery occlusion. Patients clinically presenting with
hypotension, elevated jugular venous pulse (JVP), and occasionally shock, all in the presence of clear lung fields
should raise the suspicion of RVI. The ST-segment elevation of ≥0.1mV in the right precordial leads V4R is a
readily available electrocardiographic sign used for diagnosis of (RVI) Right Ventricular Infarction
Electrocardiography is recognized as the most simple and readily available diagnostic tool for identification of
RVI.ECG with the right precordial leads (V3R to V4R) should be a routine part of the initial evaluation of patients
with clinical suspicion of acute inferior myocardial infarction for early recognition and treatment of right
ventricular infarction.
